J. Nick Koston a5bd718fc9 [api] Make ProtoDecodableMessage::decode() non-virtual ...

decode() is never called polymorphically - all call sites in
read_message_() use concrete types. The only indirect call site was
decode_to_message(), which also always knows the concrete type.

Convert decode_to_message() to a template so the concrete type is
preserved, allowing decode() to be non-virtual. The two classes that
override decode() (ExecuteServiceArgument, ExecuteServiceRequest) now
hide the base method, which works since all calls use concrete types.

This removes one vtable slot (4 bytes) from each decodable message
class vtable, saving ~148 bytes of flash.
